Why???? They're really not into a lot of grunting etc right now. All you're doing is letting everything know somethings up so be extra careful. Really, if you see one and he passes by out of range a grunt may turn him back...but other than that at this time of year stick that grunt tube in your pocket. Early season deer are all about food and bedding. Set up accordingly and you'll see deer. Grunt on your way home.
